CBT3251
1-of-8 FET multiplexer/demultiplexer
Rev. 3 — 16 March 2016
Product data sheet
1. General description
The CBT3251 is a 1-of-8 high-speed TTL-compatible FET multiplexer/demultiplexer. The
low ON-resistance of the switch allows inputs to be connected to outputs without adding
propagation delay or generating additional ground bounce noise.
When output enable (OE) is LOW, the CBT3251 is enabled. S0, S1 and S2 select one of
the Bn outputs for the A input data.
The CBT3251 is characterized for operation from 40 C to +85 C.
2. Features and benefits
